Lesson 10

Using Data Displays to Find Associations

View Student Lesson

Lesson Narrative

In this lesson, students use two-way tables, bar graphs, and segmented bar graphs to decide whether there is evidence of an association in categorical data or not (MP4).


Learning Goals

Teacher Facing

  • Create a two-way table and a segmented bar graph that represent relative frequencies, and interpret (orally) the frequencies in context.
  • Determine (in writing) whether categorical data has a positive, negative, or no association using a relative frequency table or segmented bar graph, and justify (orally) the reasoning.

Student Facing

Let’s use data displays to find associations.

Required Materials

Required Preparation

Use the data from the previous lesson’s cool-down to build a two-way table of students’ responses. Provide access to materials for students to create their own segmented bar graphs including colored pencils and straightedges.

Learning Targets

Student Facing

  • I can create relative frequency tables, bar graphs, and segmented bar graphs from frequency tables to find associations among variables.
